[ Alberto Aguirre ]
Fix not compositing the client's last posted buffer (LP: #1294048,
LP: #1294051, LP: #1294053, LP: #1290306) In single-display cases
the number of ready buffers decreases after a buffer is acquired by
the rendering operator. Determine if there will be uncomposited
buffers before acquiring a buffer so it works for single and multi
display use cases. (LP: #1294048, #1290306, #1294051, #1294053)

[ Daniel van Vugt ]
* New upstream release 0.1.7 (https://launchpad.net/mir/+milestone/0.1.7)
  - mirserver ABI bumped to 17
  - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
  - Server API changes (AKA why doesn't my code build any more?):
    . Class "CompositingCriteria" has been removed. It's replaced by the more
      flexible "Renderable" interface. This also resulted in parameter
      changes for the Renderer and scene filtering classes.
    . The function "DisplayConfiguration::configure_output()" has been
      removed. Instead, please use the new mutable version of
      "DisplayConfiguration::for_each_output()" with which you can modify
      the output structure passed in on each iteration.
    . Exposed formerly private class "GLRenderer" and demonstrated how
      to override its behaviour in demo-shell. This area is under
      construction and may experience further major changes.
  - Added initial support for hardware (HWC) overlays to accelerate
    rendering and reduce power consumption. Not complete yet.
  - Screen rotation: Added mouse cursor rotation support, so you can now
    still control things on a rotated screen. Still missing rotation of
    the cursor bitmap itself.
  - Lots of fixes to support nested Mir servers (see below).
  - Major simplification to how surface size/position/transformation
    interact, making transformations much easier to manage and work with.
  - Bugs fixed:
    . ./cross-compile-chroot.sh: line 83: popd: build-android-arm: invalid
      argument popd: usage: popd [-n] [+N | -N] (LP: #1287600)
    . Key events sent to the wrong client (and delayed) (LP: #1213804)
    . Nested servers never receive input events (in their filters)
      (LP: #1260612)
    . Software clients crash immediately on nested servers - what(): Failed
      to mmap buffer (LP: #1261286)
    . MirMotionEvent lacks local coordinates. Reports only screen
      coordinates. (LP: #1268819)
    . Nested Mir crashes with - what():
      MesaNativePlatform::create_internal_client is not implemented yet!
      (LP: #1279092)
    . clients fail to find some libraries if mir installed via "make install"
      (LP: #1285566)
    . Nested server hangs with multimonitor and internal clients.
      (LP: #1287282)
    . [regression] Multi-monitor frame sync no longer works (not
      synchronized), and frames skip/jump/stutter (LP: #1288570)
    . Mir FTBFS: /usr/bin/ld: cannot find -lmirtestdraw (when cmake ..
      -DMIR_ENABLE_TESTS=OFF) (LP: #1283951)
    . nested Mir library calls next_buffer() during startup (LP: #1284739)
    . Building Mir produces lots of warnings from GLM headers about
      deprecated degrees values vs radians (LP: #1286010)
    . [enhancement] screencast of a single window (LP: #1288478)
    . Nexus4 + mir_demo_client_eglplasma starts to stutter after a while
      (LP: #1189753)
    . --host-socket documented default argument isn't used as default
      (LP: #1262091)

* Cherry-picked from future release 0.1.7:
  - Enhancement: options: Make it easier to customize DefaultConfiguration
  - Bug fix: Don't pass a parameter to bash's popd command. It doesn't expect
    one and will return an error from cross-compile-chroot.sh. (LP: #1287600)
* New upstream release 0.1.6 (https://launchpad.net/mir/+milestone/0.1.6)
  - mirserver ABI bumped to 16.
  - Server API changes:
    . Report classes have moved to new namespaces/components. Please
      consult the server headers.
    . General clean-ups and virtual function changes affecting the ABI
      (a rebuild is required for all shells).
  - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
  - Add new feature: Screen recording ("screencasting") as demonstrated by
    the new mir-util "mirscreencast".

  - Bugs fixed:
    . Exceptions thrown from within compositing threads were untraceable,
      resulting in a bunch of undebuggable crash reports (LP: #1237332)

    . nested render_surfaces fails on N4 [std::exception::what: Failed to
      compile vertex shader:] (LP: #1284597)
    . examples: correct "fullscreen-surfaces" option. (LP: #1284554)
    . Fix mutex data race reported by helgrind in integration test:

      (LP: #1281938)
    . tests: Add expectation to validate second SessionAuthorizer method
      is called wit correct parameter. (LP: #1218436)
    . Set field "current_format" when sending a display config to the
      server. (LP: #1277343)
    . Fix crash in android devices by working around a subtle threading
      bug, use a dummy thead_local array to push the gl/egl context TLS
      into a region where the future wait code does not overwrite it.
      (LP: #1280086)
    . compositor: calling SwitchingBundle::force_requests_to_complete()
      can be a no-op when there are no requests. (LP: #1281145)
    . tests: Don't emit an "add" uevent manually when adding a device
      (LP: #1281146)
    . config: reduce size of default RPC thread pool. (LP: #1233001)

* New upstream release 0.1.4 (https://launchpad.net/mir/+milestone/0.1.4)
  - Fixed snapshotting and flicker problems for Unity8 on various Nexus
    devices.
  - Enhanced reporting of performance information:
    . Report input latency in InputReport/InputReceiverReport.
    . Added a CompositorReport for logging compositor performance and state.
  - Added a new package "mir-utils" containing new tools:
    . mirping: Displays round-trip times between client and server
    . mirout: Displays the monitor layout/configuration details
  - Added GL texture caching to improve performance when multiple surfaces
    are visible.
  - Added opacity controls to mir_demo_server_shell
  - Mir server ABI bumped to 13. Client ABI bumped to 5.
  - Removed lots of Android headers, replaced by build-dep: android-headers
  - Added support for translucent nested servers.
  - tests: Fix unitialized values and incorrect fd closing loops
  - Fix unitialized values and incorrect fd closing loops.
  - client: Add basic MirScreencast C API.
  - config: start moving default values for config options from all the
    call sites to the setup
  - tests: Provide a helper for running clients with a stub ClientPlatform.
  - android: split out HWC layers into their own file and add a
    mga::CompositionLayer type that depends on the interface mg::Renderable.
  - client: Add basic MirOutputCapture class.
  - client: Don't create mesa ClientBuffer objects from invalid
    MirBufferPackages.
  - Optimize surface resizing to avoid doing anything if the dimensions
    are unchanged.
  - SwitchingBundle - add operator<< for debugging.
  - support hwcomposer 1.2 for android 4.4 on nexus 4 (which needs hwc1.2
    support). This patch adds hwc1.2 device construction, as well as progs
    the 'skip' layer in HWC to the buffer properties of the framebuffer.
  - demo-shell: Add simple keyboard controls to rotate outputs; Ctrl +
    Alt + <arrow-key>. Fixes: https://bugs.launchpad.net/bugs/1203215.
  - frontend: exposing internals of the RPC mechanism to enable custom
    function calls to be added.
  - Make udev wrapper into a top-level citizen
  - compositor: ignore double requests to start or stop the
    MultiThreadedCompositor.
  - Add DisplayBuffer::orientation(), to tell the Renderer if we need it
    to do screen rotation in GL (for platforms which don't implement
    rotation natively) Fixes: https://bugs.launchpad.net/bugs/1203215.
  - graphics: add an post_update function that takes a list of renderables
    to the display buffer. This will let the display buffer take advantage
    of full-surface overlays on android.
  - android-input: Improve debug output
  - the stock qcom 8960 hwcomposer chokes on getDisplayAttributes if the
    submitted arrays are not at least size 6. patched the qcom android 4.2
    hwcomposer driver on the ubuntu touch images to work properly, but
    causes us problems with in-the wild drivers, and the new 4.4 drivers.
    Make sure we always submit a larger-than-needed array to this function.
  - frontend: refactoring to make it easier to expose the underlying RPC
    transport on the server side.
  - Don't assume pressure value is zero if not yet known
  - build: Expose options to allow building but not running tests by default.
  - Translucent Server which prefers a transparent pixel format
  - frontend: refactor ProtobufMessageProcessor to separate out generic
    response sending logic from specific message handling.
  - client: expose the part of the client RPC infrastructure needed for
    downstream to prototype their own message sending.
  - Bugs fixed:
    . unity8 display flickers and stops responding on Nexus 7 (grouper)
      (LP: #1238695)
    . Mir gets textures/buffers confused when running both scroll and flicker
      demos (LP: #1263592)
    . Some snapshots on Nexus10 upside-down (LP: #1263741)
    . mir_unit_tests is crashing with SIGSEGV in libhybris gl functions
      (LP: #1264968)
    . Some snapshots on Nexus10 have swapped red/blue channels (LP: #1265787)
    . Bypass causes some non-bypassed surfaces (on top) to be invisible
      (LP: #1266385)
    . helgrind: Possible data race - MirConnection::mutex not used
      consistently (LP: #1243575)
    . helgrind: Lock order violated (potential deadlock) in
      ConnectionSurfaceMap (LP: #1243576)
    . helgrind: Possible data race - inconsistent locking in PendingCallCache
      (LP: #1243578)
    . helgrind: Lock order violated in
      mir::client::ConnectionSurfaceMap::erase(int) (LP: #1243584)
    . [enhancement] Allow a Mir nested server to have a transparent
      background (LP: #1256702)
    . Compiling without tests fails (-DMIR_ENABLE_TESTS=NO) (LP: #1263724)
    . examples, doc: Make it clear and consistent how to use
      a non-root client with a root compositor endpoint.
      (LP: #1272143)
    . Avoid linking to umockdev on platforms (android) which don't yet
      use it. This allows mir_unit_tests to run on touch images again
      (LP: #1271434)
    . Workaround for N4 nested server issue. This change removes
      mir_pixel_format_bgr_888 - HAL_PIXEL_FORMAT_RGB_888 from the
      list of supported pixel formats on android. (LP: #1272041)
    . Don't ask glUniformMatrix4fv to transpose your matrix. That option
      was officially deprecated between OpenGL and OpenGL|ES. And some
      drivers like the Nexus 10 don't implement it, resulting in incorrect
      transformations and even nothing on screen! (LP: #1271853)
    . Fixes: bug 1272143 (LP: #1272143)
    . fix integration test failure on the galaxy nexus that was due to
      creating two surfaces and registering the same buffer twice. Fixes:
      (LP: #1272597)
    . Implement screen rotation in GLRenderer, for platforms
      which can't do it natively in DisplayBuffer.
      (LP: #1203215)
    . Add an "orientation" field to output structures in preparation for
      screen rotation. It's not yet functionally wired to anything.
      (LP: #1203215)
    . Only use SwitchingBundle::last_consumed after it has been
      set. Otherwise SwitchingBundle::compositor_acquire could follow a bogus
      code path. (LP:#1270964)
    . tests: Override configuration to avoid creating an (unused)
      filesystem endpoint for connections when using InProcessServer.
      (LP: #1271604)
    . frontend: ensure that BasicConnector threads don't exit
      immediately. (LP: #1271655)

* New upstream release 0.1.2
  - graphics: android: improve interface for mga::DisplayDevice so its
    just concerned with rendering and posting.
  - surfaces: rename "surfaces" component to "scene".
  - surfaces, shell: Migrate Session data model from shell to surfaces.
  - graphics: change fill_ipc_package() to use real pointers.
  - mir_client_library.h: Fix typo "do and locking" should be "do any
    locking".
  - API enumerations cleanup: Remove slightly misleading *_enum_max_
    values, and replace them with more accurate plural forms.
  - test_android_communication_package: Do not expect opened fd to be >0,
    we may have closed stdin making this a valid value (LP: #1247718).
  - Update docs about running Mir on the desktop to mention new package
    ubuntu-desktop-mir.
  - offscreen: Add a display that renders its output to offscreen buffers
  - graphics: android: fix regression for hwc1.0 devices introduced in r1228
    (LP: #1252433).
  - OffscreenPlatform provides the services that the offscreen display
    needs from the Platform.
  - graphics: android: consolidate the GLContexts classes in use.
  - Fix uninitialized variable causing random drm_auth_magic test
    failures. (LP: #1252144).
  - Add a fullyish functional Udev wrapper. This currently sits in
    graphics/gbm, but will be moved to the top-level when input device
    detection migrates.
  - Add resizing support to example code; demo-shell and clients.
  - eglapp: Clarify messages about pixel formats (LP: #1168304).
  - Adds support to the MirMotionEvent under pointer_coordinates called
    tool_type. This will allow clients to tell what type of tool is
    being used, from mouse/finger/etc. (LP: #1252498)
  - client,frontend: Report the real available surface pixel formats to
    clients. (LP: #1240833)
  - graphics: android: 1) change hwc1.1 to make use of sync fences during
    the compositor's gl renderloop. Note that we no longer wait for the
    render to complete, we pass this responsibility to the driver and the
    kernel. 2) support nexus 10. (LP: #1252173) (LP: #1203268)
  - shell: don't publish SurfacesContainer - it can be private to shell.
  - gbm: Don't mess up the VT mode on setup failure Only restore the
    previous VT mode during shutdown if it was VT_AUTO.
  - Fix a crash due to a failed eglMakeCurrent() call when in nested mode.
  - shell: unity-mir uses shell::FocusSetter - make the header public again
  - Add resize support to client surfaces (mir::client::MirSurface).
  - graphics: android: support 'old aka 2012' nexus 7 hwc (nvidia tegra3
    SoC) better. (LP: #1231917)
  - Add resize support to *ClientBuffer classes. Now always get dimensions
    from the latest buffer package.
  - android: support driver hooks for the Mali T604 (present in nexus 10)
  - Add width and height to the protocol Buffer messages, in preparation
    for resizable surfaces.
  - surfaces, shell, logging, tests: don't publish headers
    that can be private to surfaces. surfaces/basic_surface.h,
    surfaces/surface_controller.h and shell/surface_builder.h
  - examples: Restore GL framebuffer binding when destroying the render
    target
  - examples, surfaces, shell: remove render_surfaces dependency on
    BasicSurface
  - geometry: remove implementation of streaming operators from headers
    (LP: #1247820)
  - Eliminate the registration order focus sequence, folding it's
    functionality in to the session container.
  - Ensure the session mediator releases acquired buffer resources before
    attempting to acquire a new buffer on behalf of the client. This fixes
    performance regression (LP: #1249210).
  - Some cleanups to test_client_input.cpp.
  - Factor out a bunch of "ClientConfigCommon".
  - Small cleanup to session container test to increase encapsulation.
  - shell, surfaces: Another step in "fixing" the surfaces hierarchies -
    only publish interfaces and putting the data model into surfaces.
  - graphics: android: HWC1.1 use EGL to get further information about
    the framebuffer pixel format.
  - Fix FTBS using use_debflags=ON (building for android-armhf).
    (LP: #1248014)
  - Add a client input receiver report.
